Back in high-school, we used to open a bag of M&M's and trail them through the store. It usually took a few minutes, but the mexican kids would come crashing around the corner, pushing one-another, and eating the M&M's off of the floor. It was always such a funny spectacle. Me and the other perpetrators were escorted out of Wal-Mart once for this little stunt. Now, there are so many mexicans in that same store that I could be held legally liable for a stampede if I repeated the prank.
